Funny Hide NAT for FW1_ica_services after install Jumbo 189 HF R80.10

[Uwe_Knoetsch]

Hello,

after we install the Jumbo HF 189 on a VSX Gateway Cluster we get problems with central managed SMB Appliances there are connect to a MDM CMA trought this VSX Firewall.

We see in the log that packets with service FW1_ics_services are from this moment the firewall hidden by an implicit NAT behind the gateway. But packets with service CDP (TCP/18191) they arn't hide-natted.

my Questions: Is this a new special function inside Jumbo HF 189? Has any CheckMates member informations about this new uncomfortable behavior?

The god thing is: after we install a no-NAT Rule for the destiantion (the MDM-CMA) all is fine.

Regards Uwe
